Can't Shift into Lowest 2 Gears?
I just installed a 8-speed Shimano Altus shifter, derailleur and Cassette. Everything seemed to be working fine when I was initially adjusting the derailleur but then when i tried to shift to the top 2 gears it stopped, I don't mean the chain stopped but the shifter shifted, I mean the chain stopped because it's like the shifter isn't a 8-speed shifter, it's like it's a 6 speed shifter, after I get to 3rd gear it just stops and the shifter won't move. What do you guys think may be going on? Is it just a matter of needing more adjusting, loosening the cable, do you think i got a defective shifter maybe incorrect indexing? I do plan on taking it to my LBS tomorrow but I'd like to hear what you guys think may be happening because if it's something I could do and save some money by not going to the LBS that would great. Again it's a shimano Altus 8-speed derailleur, Altus 8-Speed Trigger shifter and Altus 8-speed cassette. The shifter won't go past 3rd gear no matter how hard I press it.

take the cable loose from the derailleur and make sure the shifter will go through all clicks starting at the first. there will be seven clicks ending in eigth gear

Presumably you installed a new cable and housing, too. Perhaps a housing ferrule wasn't set all the way onto the housing. The first shifts compressed it into place, and now it's acting like the cable is too long. Try resetting the cable again. First tug on it pretty hard a couple of times to set all the ferrules into place, and the ferrules into the stops. This is a good time to practice limiting the torque on the pinch bolt--repeated tightening of the bolt will fray the cable.

Can we assume you mean the two largest cogs, a.k.a. the two lowest gears? It sounds like you just need to adjust the limit screw on the derailleur.

Does it give you extra shifts going in the other direction? You may not have had it set to the end of the ****ing when you installed the cable. Or limit screw as mentioned.
